DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0034] A lighter assembly incorporated with an adapter according to a first embodiment of the present invention is shown in FIG. 1, and generally designated as 100. The lighter assembly 100 includes a lighter 102, two plastics casing halves 104 a, 104 b, and a clip 106. The lighter 102 is a conventional lighter with a body 108 for containing fuel under pressure. A flame is produced when a button 110 is pressed to move in the direction indicated by the arrow M, which is parallel to the longitudinal axis of the lighter 102, relative to the body 108 of the lighter 102.

[0035] On the lateral edges of the casing half 104 a are two narrow protruding rims 112 (of which only one is shown in FIG. 1), which co-operate with two troughs 114 (of which, again, only one is shown in FIG. 1) along two lateral edges of the casing half 104 b, to allow the casing halves 104 a, 104 b to slide relative to each other when they are engaged with each other. In particular, the protruding rims 112 are received in the respective trough 114 for relative sliding movement. The rim 112 is shorter than the trough 114, at least by the distance required to be travelled by the button 110 for producing a flame. To enhance sliding movement of the body 108 of the lighter 100 relative to the inner surface 116 of the casing half 104 b, two elongate smooth pieces 118 are fixed to respective correspondingly shaped and sized parallel recesses 120 (of which only one is shown in FIG. 1) in the inner surface 116.

[0036] As shown in FIG. 4, and more clearly in FIG. 4A, the clip 106 has two oppositely spaced ledges 122 (of which only one is shown in FIG. 1) received within a rectangular aperture 124 of the casing half 104 b, for fixing the clip 106 to the casing half 104 b. The clip 106 also has two hooks 126 (of which only one is shown in FIG. 1) which, when the casing halves 104 a, 104 b are engaged with each other, are received within a respective channel 128 on an outer surface 130 of the casing half 104 a, thus effecting engagement between said casing halves 104 a, 104 b, while allowing relative lengthwise sliding movement between the casing halves 104 a and 104 b.

[0037] In order to enhance, during use, gripping of a user finger of the outer surface 130 of the casing half 104 a, a corrugated finger pad 132 is provided on the outer surface 130 of the casing half 104 a, for frictional engagement with the user finger, e.g. thumb.

[0038] The casing half 104 a has a bent lower end 136 which, when the lighter assembly 100 is properly assembled, constitutes a stopper that acts on a lower end of the body 108 of the lighter 102. The casing half 104 b also has a bent upper end 138 which, when the lighter assembly 100 is properly assembled, constitutes a stopper that acts on an upper surface of the button 110 of the lighter 102.

[0039] Turning now to FIGS. 2 and 3, it can be seen that when the casing halves 104 a, 104 b and the lighter 102 are assembled to form the lighter assembly 100, most of the lighter 102 is enclosed by the casing halves 104 a, 104 b, except that an end 134 of the lighter 102 at which a flame is produced is exposed to the outside environment. When the casing half 104 a is pushed upwardly relative to the casing half 104 b, because of the stopping function of the bent lower end 136 of the casing half 104 a and the bent upper end 138 of the casing half 104 b, the bent lower end 136 and the bent upper end 138 will be moved towards each other, such that the button 110 of the lighter 102 will be pushed downwardly relative to the body 108 of the lighter 102, along a path parallel to the longitudinal axis of the body 108, to produce a flame, as shown in FIG. 3.

[0040] A lighter assembly incorporated with an adapter according to a second embodiment of the present invention is shown in FIGS. 5 and 6, and generally designated as 200. The lighter assembly 200 includes a lighter 202, two casing halves 204 a, 204 b, and an engagement member in the form of a closed loop 206. The lighter 202 is a conventional lighter with a body 208 for containing fuel under pressure. A flame is produced when a button 210 is pressed to move downwardly relative to the body 208 of the lighter 202, and parallel to the longitudinal axis of the lighter 202.

[0041] As can be seen in FIG. 7, on an outer surface 210 of the casing half 204 a are a number of short protrusions 212 for enhancing frictional engagement of a user finger with the casing half 204 a. Similarly, as can be seen in FIGS. 8 and 9, an outer surface 214 of the casing half 204 b is corrugated, again for enhancing frictional engagement of a user finger with the casing half 204 b. FIGS. 7 to 9 also show the way in which the lighter assembly 200 is assembled.

[0042] The lighter 202 is firstly placed in the cavity of the casing half 204 b, as shown in FIG. 7. The casing half 204 a is then engaged with the casing half 204 b, as shown in FIG. 8. The engagement loop 206 is then placed over the engaged casing halves 204 a, 204 b until the engagement loop 206 is engaged with the casing half 204 b, as shown in FIG. 9, in a manner to be discussed below.

[0043] FIGS. 10 to 14A show various views of the casing halves 204 a, 204 b and engagement loop 206 as engaged with one another, in the absence of the lighter 202, for clarity purpose. As can be seen in FIG. 12, when the engagement loop 206 is engaged with the casing halves 204 a, 204 b, a protrusion 218 of a lip portion 220 of the engagement loop 206 is received within a hole 222 of the casing half 204 b. FIGS. 13 and 13A show the dovetail engagement between the engagement loop 206 and the casing half 204 b. FIGS. 14 and 14A show the engagement between the casing halves 204 a, 204 b, which allow the casing halves 204 a, 204 b to exhibit relative sliding movement.

[0044] A lighter assembly incorporated with an adapter according to a third embodiment of the present invention is shown in FIGS. 15 and 18, and generally designated as 300. The lighter assembly 300 includes a lighter 302, two casing halves 304 a, 304 b, and two engagement members, each in the form of a closed loop 306. The lighter 302 is a conventional lighter with a body 308 for containing fuel under pressure. A flame is produced when a button 310 is pressed to move downwardly relative to the body 308 of the lighter 302, and parallel to the longitudinal axis of the lighter 302. As can be seen in FIG. 16, there are two pairs of holes 312 on the casing half 304 b, each pair to be engaged with one of the loops 306, in a manner to be discussed below.

[0045] FIGS. 19 to 21A show various views of the casing halves 304 a, 304 b and the loops 306 as engaged with one another, in the absence of the lighter 302, for clarity purpose. As can be seen more clearly in FIGS. 20A and 21A, each of the loops 306 has two protrusions 316, each to be received within one of the hole 312 on the casing half 304 b, for engaging the casing halves 304 a, 304 b.

[0046] It is found in practice that the movement of the hand and fingers required to effect relative movement between, respectively, the casing halves 104 a and 104 b, 204 a and 204 b, and 304 a and 306 b cannot be performed by small children, e.g. ones under the age of three. The lighter assemblies 100, 200 and 300 are thus effectively child-resistant lighters at least hindering unwanted operation by small children. The casing halves 104 a and 104 b, 204 a and 204 b, and 304 a and 304 b also respectively collectively act as adapters suitable for converting an otherwise non-child-resistant lighter into a child-resistant lighter.
